An income annuity turns a portion of your savings into a guaranteed stream of payments — potentially for life — directly addressing the risk of outliving your money. It's one tool for building a retirement “paycheck,” best used to cover essential expenses as a floor beneath the rest of an income plan, not as a replacement for all your assets.
Longevity risk
The problem it solves
The hardest question in retirement isn't “how much have I saved” — it's “how do I turn savings into income that lasts as long as I do, without knowing how long that is.” Portfolios can be drawn down too fast or too slowly; markets don't cooperate on schedule. An income annuity answers part of that by handing the longevity risk to an insurer in exchange for a guaranteed payment.
The floor-and-growth idea
How it fits an income plan
A common, sensible structure covers your non-negotiable expenses — housing, food, insurance, utilities — with guaranteed income: Social Security first, then an income annuity to fill any gap. The rest of your savings stays invested for growth, inflation protection, and flexibility. That way you have certainty where you need it and upside where you can afford risk.
- Immediate annuities begin paying right away — useful at the start of retirement.
- Deferred income annuities start later, sometimes much later, as longevity insurance for advanced age.
- Payout options (life-only, joint, period-certain, refund) trade income size against legacy protection.
Honest costs
The trade-offs to weigh
Guaranteed income usually means giving up access to and control of the lump sum. Basic lifetime payouts may leave little for heirs. Inflation can erode a level payment over a long retirement unless you add a cost-of-living feature (which lowers the starting amount). And the guarantee is only as strong as the carrier. None of these is disqualifying — they're the reasons to size the annuity to a specific job rather than over-committing.
When this is the wrong tool — and what can go wrong
Using an annuity for income is the wrong move when:
- You annuitize everything and leave yourself without liquidity for emergencies or opportunities.
- You need the money to stay accessible or to pass to heirs, and you choose a life-only payout anyway.
- Inflation over a long retirement isn't addressed and a level payment slowly loses purchasing power.
- It's sold as a cure-all rather than the floor beneath a diversified plan.
- The carrier's financial strength and the payout options aren't examined before committing.
